영문 초록

Seven soybean varieties, from the extreme early to the extreme late variety, and F₁ plants of twenty-one crosses were used as the materials, F₁ plants showed the intermediate days to flowering between early flowering parent and late flowering parent, respectively. It was calculated that days to flowering of F₁ plants in each cross are as; F₁=P₁+0.62R, where in the case of P₁ denote the days to flowering of early flowering parent and R denote the range from the days to flowering of the late flowering parent (P₂) to the days to flowering of the early flowering parent (P₁) in each cross. It was also recognized that partial dominance was exhibited by flowering in all parents used as the crossing materials, and there were many dominant genes in the late flowering varieties than the early flowering varieties. The extreme late flowering variety, Tamanishiki, would lie have more dominant genes in flowering than the late flowering varieties, Ulsan or Tamaokiwase, and the extreme early flowering variety, Blackhawk, would be have more recessive genes in flowering than the late flowering varieties.
